If you want to buy a new air conditioning unit, one of the main considerations is whether to purchase an inverter air conditioner or a non-inverter unit.
Inverter units claim to provide more energy-saving effects and cool the room faster than non-inverter units. However, inverter units are also more expensive.
To help you determine whether the inverter unit is worth the extra cost, please continue reading.
How does the air conditioner work?
To understand whether you need invertor or non invertor air conditioning, you need to understand the basics of air con.
The basic form of air conditioner is composed of external equipment and internal equipment, which are connected by pipes. The duct does not carry cold air. Instead, the pipe contains a special gas called a refrigerant (imagine a cooling gas like blood in your body; it will flow back and forth, but it will not be missed):
- External equipment (called compressor) cooling gas
- The cold air flows into the room through the duct
- The blower blows ordinary air through the cold pipe. This makes the air cooler
- Cool air cools your room
The compressor units of all air conditioning units are located outside the windows or on the balcony, and blowers or fans are installed in the rooms.
The external compressor and internal blower are connected by pipes. And air conditioning gas (called refrigerant) flows back and forth in these pipes.
As the name suggests, an external compressor is used to “squeeze” the refrigerant from gas to liquid. This releases heat and releases it to the external environment. Then, the compressed refrigerant is guided to the internal unit.
In the internal unit, the refrigerant is allowed to expand and become a gas. When this happens, it absorbs the heat of the surrounding air, making it cooler.
Cold air blows into the room.
The expanded refrigerant is sent back to the external compressor for another round of “squeezing.” And this cycle is continue and continue.
What is an inverter air conditioner?
Air conditioning inverter means that the external compressor can be decelerated or accelerated.
This is the opposite of a non-inverter, where the compressor can only run at one speed.
When you turn on the air conditioner and set the temperature to 26 degrees Celsius (for example), the compressor will start running at full speed. The same applies to inverter or non-inverter air conditioners.
The difference is the time it takes for the room to reach the desired temperature.
For air conditioners without frequency converters, the external compressor unit will be completely shut down. The internal blower will continue to blow air.
As the compressor unit stops, the room will gradually begin to reheat. When this happens, the external device will restart at full speed.
Usually, you can hear this initial stop operation occurring at night, which may interfere with your sleep.
For inverter air conditioners, the external compressor unit will not shut down completely. Instead, it will slow down and use less energy to maintain temperature.
Invertor Aircon provides greater energy savings
According to air conditioner manufacturers, due to frequent intermittent operation, air instead of inverter consumes more energy.
However, because the inverter can slow down to maintain room temperature, the air conditioner manufacturer says that you can save up to 30% of energy compared to non-inverter air.
If so, why do I keep hearing about inverter air conditioners actually increasing electricity bills?
In some cases, inverter air conditioners may not help save energy.
An example is if you install a poor quality air conditioner for a very large room.
Whether you have invertor or non invertor aircon in this room, both should continue to run at full speed to cool the room. Too much heat increase prevents the air conditioner from reaching the required temperature.
Some reports even pointed out that if you use inverter air conditioners for less than 8 hours a day, you can only save this energy. If you use 24/7 air conditioning, you may not be able to save any energy compared to non-frequency converters.
Is it more expensive to maintain inverter air conditioners?
not really. Between inverter units and non-inverters, the price of aviation services are only around SG3 per unit. Suppose you need toservice your air-condition 4 times a year, the difference is only SG13, which is almost the same as saving 1 month of energy.
In addition, since inverter air conditioners should not continue to start and stop (compared to non-inverter air conditioners), the compressor and motor wear less. This helps to extend its life and save replacement
According to reports, Aircon inverters have better energy-saving effects than non-inverter air. This is because they can slow down and accelerate the compressor to maintain the same cooling level.
Aircon is not an inverter, on the contrary, it can only run at one speed. When the required temperature is reached, the temperature will disappear. When it gets hot, it will open.
This frequent pause operation consumes more energy than the air of the inverter. Due to this feature, invertor aircon claim to save 30% of energy.
However, inverter aircon is more expensive. According to our calculations, compared with non-inverters, the extra cost will be recovered within one and a half years, after which you will get continuous energy savings. But this is assuming you have a space where startup operations often stop.
